Open Source alternatives to Tendenci - with modifications

Proprietary / Closed Source alternatives to Tendenci

Please note that some have free "trials", but no source code access. And we are not aware of any other AMS/MMS systems for associations and non-profits that have immediate full database access and download like Tendenci does.

The list is broken into three parts. The first list is software for Associations and NPOs that have encryption on their primary site. We take security seriously. SSL is baseline to protect your membership and for SEM. Therefore, we view these alternatives to Tendenci as better choices than those without encryption on their own sites.

The second list below is comprised of viable AMS alternatives to Tendenci that aren't running encryption on their own sites. Not running encryption on their sites does *not* mean they aren't encrypting their clients' sites or their transaction pages. It just means their leadership is kinda "meh" about security. Hopefully that will change, as every association deserves secure sites running secure software.

*** At the time we are writing this page Tendenci, as far as we know, is the only actual FOSS option that we can find besides CiviCRM. So if you know of a truly "free and open source software" product that meets the needs of large associations (over 100k people minimum seems like a fair baseline), let us know so we can add you!
